ARBY W. BAILEY, OF IRON RIVER, WISCONSIN.

RAILROAD GATE.

Application filed November 18, 1924. Serial No. 750,687.

T all whom it may concern:

Be it known that I, ABBY WV. BAILEY, a

' citizen of the United States, residing at Iron "approaching a crossing,

River, in the county of Bayfield and State of Wisconsin, have invented certain new and useful Improvements in Railroad Gates, of

which the following is a specification.

V This invention relatesto gates for railroad crossings and has for its object the provision of means whereby, when a train is a barrier wlll be dlSPOSBd across the road to bar the entrance "of pedestrians or vehicles upon the railroad ing. The inventionalso seeks to provide such an automatically operated gate or barrier in which the working parts will be simple in arrangement and, therefore, not apt to get out of order and which will be so arranged as to be operated'under allconditions. The invention is illustrated. in the accompanying drawings and will be hereinafter fully set forth. I k

In the drawings:

Figure 1 is a side elevation of a rail- 7 road'gate embodying my improvements;

Fig.2 is a plan view of the same;

Fig. 3 is an enlarged horizontal section on the line 3-3 of Fig. 1, and

Fig. 4 is a vertical section on the line 4.-4= of'Fig. 3.

In the drawings, the reference numeral, 1

indicates a portion of a railroad track of the usual construction, and Qindicates a porject over the crossing. anchored in any convenient manner and the tion of a road crossing the track. In carryingv out my invention, I erect a post 3 adj acent the. side of the crossing and adjacent the track "so that a swinging bar or gate 45 mounted upon the post will extend parallel with the track and when lowered will pro- This post may be bar or gate l is pivotally supported in a bracket 5 secured on the side of the post, a

Ecounter-Weight 6 being secured upon the shorter arm of the gate, as shown.

This weight should be of such size as to normally hold the gate in raised position so that, when the forces operating to lower the gate are removed, the gate will-be automatically raised. Mounted in any convenient manner upon the post is a guide pulley 7 and afcable 3 extends around the said guide pulley and 1S secured to the gate, as clearly shown.

The pulley 7 may be protected against'the I weather by any convenient form of housing,

but such housing has not been shown in the drawings in order'to more clearly illustrate the working parts. From thepulley 7, the

cables extends away from the 'c'rossingf arallel with the track andis supporte; in

guide post s 9 in a well-known manner. The remote endof thejcable passes into a housing 10 which is preferablyinthejform of a cylindrical tube provided with sidefia-nges or similar members 11 through which jfastening devices are inserted t-o ancho'r the housing upon extensions of the railroad ties. Vithin the housing 10 is a slide or crosshead 12 which may conveniently be a circular disk of any material possessing the requisite strength. The end of the cable 8 is attached to the disk by engagement with a hook or eye 13 disposed centrallyfoff the disk and' firmly' united therewith. At the oppos te side-of the disk is a looporeye'lt in which is engaged one end of a coileditension spring 15 which extends to theopposite end of the housing andis there secured by engagement with a hook or staple 16 firmly,

secured in the-housing, as shown most clear ly in Fig. 3. Obviously, the spring15 tends constantly to contract and thereby exerts'a pull upon the cable whichtends'to lower the gate. The spring is normally heldektended so that the'gate will be in raised position by dogs or restraining levers 17 mountedupon opposite sides of the housing 10 and arranged to he operated by ap'assin'g train.

These levers, as clearly shown in Fig, 3-, are.

fulcrumed between their ends upon lugs or brackets 18 formed upon the sides of the housing, 1 and expansion springs 19 are disposed between the housing andjthe levers to hold them normally in working position.

The heads or worki g ends of the levers are provided with lugs or hooks 20 which are adapted to engage against the c'rosshead or slide 12; and thereby hold'the sameagainst the force of the spring 15, as willbe readily v understood upon, reference to Fig. 3, slots 21 being provided irrthe sides of thejjhousing to permit the lugs: or hooks 2Qfto pass into the housing and assume their working positions in en-gagement'with the cros'shead.

A link 22 extends over the housing 10 and has one end pivotally engaged in the working end of that lever which is nearer the track and its opposite end engaged in the free end of the more remote lever so that,-

at an angletoeach other and is fulcrumed at its angle, as shown at 24:. The longer arm of this lever terminates near the track in position to be struck by astriker arm of any desired form mounted upon a locomotive and it is normally held in this position by a contractile spring 25 attached to the lever and a fixed element 26 of any approved type. Adjacent the longer arm of the lever is a stop 27 which limits the movement of the lever under the influence of the spring 25 so that it cannot assume an inoperative position. The shorter arm of this trip lever carries a roller 28 which is adapted to ride upon the free end of the adjacent lever 17 and the parts are so proportioned and arranged that the are described by this roller or the free end of the trip lever will intersect the vertical plane of the adjacent surface of the lever 17 so that, when the trip lever is rocked, the free end of the lever 17 will be swung toward the housing 10 and the head or lug 20 released from the crosshea'd12, a like movement of the remote lever 17 being effected through the link 22. When the crosshead 12 is thus released, the spring 15 at once contracts and the gate is lowered.

Near the post 3, I provide a housing 29 in which is mounted a guide roller 30 and adjacent the said housing is mounted a trip v arm 31 which has one end disposed in the path of the striker arm upon an oncoming locomotive and its opposite end attached to a short cable 32 which passes forwardly from the lever and around the roller 30 and then rearwardly to be connected with the main operating cable 8. The lever 31, as shown clearly 'in Figs. 1 and 2, is disposed n near the crossing and, when it is struck by a locomotive, it will exert a pull through the auxiliary cable 32 upon the main cable 8 so as to impart reverse movement to the said main cable 8 and permit the gate to rise under the influence of the weight 6. Of course, when the trip lever 23 has been freed of the locomotive or the striker thereon, the

springs 19 and 25 at once return it and the levers 17 to their normal working positions with the lugs or heads 20 projecting into the housing 10. To prevent the said lugs stopping the crosshead 12 before the gate is fully raised, the edges of said lugs presented main in that position until the train is passing over the crossing when it will be automatically released and permitted to rise. 1t-

will, of course, be understood that the gate or barrier may be provided at each side of the track and at each side of the crossing F and that the plurality of gates so provided may be connected through suitable gearingto be controlled and operated simultaneous ly whenever a train approaches in either direction. illustrated as they involve merely duplication of the parts shown and described and will readily occur to skilled mechanics.

It will be understood that the working Such variations, however, are not parts, in actual practice, are all enclosed so as to be protected from the elements, only the working ends of the leversbeing exposed. It' will also be understood that at night a lantern will be hung upon the gate.

Having thus described the invention, I 2
